The Kastel Formula

“There’s no such thing as bad weather – only bad clothing.” In Norway, that’s more than a saying — it’s how we live.

We’ve grown up dressing for unpredictable conditions, trusting a simple formula: waterproof protection on the outside, and wool for warmth and breathability. From fishermen at sea to kids in the playground — it’s part of who we are.

At Kastel, we’ve adapted that mindset into footwear. We combine waterproof PU and temperature-regulating wool to make shoes built for everyday life — no matter the weather.

Raised by Weather. Built for every day.

Explanation of Kastel's sustainability efforts

Innovation for Sustainability:

Nature Lab

The Nature Lab Process:

Sustainability is complex. Just like 30% less sugar isn’t sugar-free, we don’t just claim to be sustainable. We take action!

Our approach involves bold experiments in materials, design, and business models across three phases. Viable ideas become pilot products, and successful pilots set new standards and innovations.

Sustainability in Kastel shoes thrives on aligned, ongoing efforts.

Some innovations from Nature Lab that this product uses

Where ideas meet weather

In our Nature Lab, we explore new ways to make shoes that perform better, last longer, and leave a smaller footprint. Here are some of the materials and concepts that have made it from lab to street.

Waterproof Uppers

Traditional waterproof membranes are effective until they fail, often due to minor wear like a small pebble puncture. Drawing inspiration from the durable PU raincoats of fishermen, we crafted shoes from this robust material. The result: footwear that withstands time and elements with increased longevity.

  • - Keeps moisture out
  • - Built to endure

Uppers in Norwegian Wool

Norwegian wool. Naturally prepared for weather. Wool is strong, breathable, and water-resistant by nature — just like the animals it comes from. We use Norwegian wool to stay close to our roots and reduce unnecessary transport. A smart material for shoes built for the outdoors.

  • - Naturally weather-ready
  • - Locally sourced, less transport

3D-Knitted Merino Wool

3D-knitted wool. Light, breathable, and easy to care for. Wool keeps your feet cool, fresh, and dry — no synthetic treatments needed. The 3D-knit construction adds airflow, reduces waste, and gives a flexible fit. And when it needs a refresh? Just toss it in the wash.

  • - Seamless everyday comfort
  • - Machine Washable

Component Reduction

Less parts. Less waste. Same performance. We’ve made it standard to reduce the number of components in every new Kastel shoe. Smarter design means less waste — without compromising on function or durability. Since 2019, every style has been built this way.

  • - Less parts, less waste
  • - Smarter shoe design

Size Insert

Smarter sizing. Less waste. Instead of producing half sizes, we developed a size insert that adjusts the fit by half a size. It helps reduce overproduction, cuts down on returns, and makes sizing more flexible — all without adding complexity to the supply chain.

  • - Reduces returns and overstock
  • - No need for half-size production

Uppers in Hemp

Hemp treated for weather. Naturally strong. We’re exploring hemp as a low-impact alternative to polyester. It's strong, breathable, and grows with less water than cotton. By treating it with natural waxes, we’ve added water resistance — without the use of harsh chemicals.

  • - Natural alternative to synthetics
  • - Weatherproofed without chemicals

Timeline section

It started with a question:

Why aren't there shoes made for Norwegian weather? From that moment, we’ve followed our curiosity — learning, testing, and building one step at a time. Here's how Kastel came to be, and where we're heading next.

1996

A seed was planted

Inspired by the skate-shoe culture of the 90s, 13-year-old Andreas Malo Dyb decides he’ll one day start a Norwegian sneaker brand.

2004 - 2007

Learning the craft

Andreas studies Industrial Design in Milan before returning to Norway to work at Dale Skofabrikk — where he learns classic shoe craftsmanship from the ground up.

2009

Mastering outdoor tech

Andreas gains hands-on experience working with Norwegian outdoor footwear brands, building knowledge in weather-specific performance.

2013 - Duro

Kastel is launched

Seventeen years after the dream began, Kastel was born — offering clean sneakers designed for Nordic weather.

2014 – Ladera

Everyday function, reimagined

Kastel releases its first summer shoe with an elastic heel. Easy to slip on, easy to love.

2015 – Madla

The first waterproof sneaker

Madla is launched — a waterproof sneaker/boot hybrid that challenges the market. No more soggy shoes or stiff boots.

2019 – Briskeby

Introducing Merino wool

Kastel launches its first Merino wool sneaker, exploring natural materials for warmth, breathability, and comfort.

2020 – Lofoten

Norwegian wool, proudly used.

Kastel’s first shoe using local Norwegian wool from the endangered Grå Trønder sheep — strong, breathable, and naturally weather-ready.

2020 – Røros

Waterproof, without membranes

A new chapter: Kastel develops its first membrane-free waterproof shoe. Lightweight, flexible, and chemical-free.

2021 – Stavern

Less parts, more purpose

Stavern is designed with just 11 components instead of 31 — lighter, stronger, and machine washable. A step toward smarter, cleaner design.

2022 – Madla Hemp

Waterproof, waxable, and natural

Madla gets a hemp update — durable, breathable, and waterproofed with beeswax for longer life and fewer synthetics.

2023 – Lofoten White

Color on demand

To avoid overproduction, Kastel creates a white wool sneaker that can be dyed to any color — every shoe has the potential to be the bestseller.

2024 – 3D Knitted

Local knitting, natural materials

Kastel develops its first working prototype of a 3D-knitted sneaker made from Norwegian wool. Locally produced, minimal waste, and full of future potential.

2025 – Kampen

The first modular shoe

Kampen introduces Kastel’s modular system: interchangeable details that let you upgrade and refresh your shoes instead of replacing them.
